[03] STORY OF THE WEEK
   DeepSeek V4 lands. 405B MoE, 32K active, MIT-license.
   Arena debut at 1,348 ELO — 4 points behind GPT-5,
   2 points ahead of Claude 4.5. Pricing: $0.27 / Mtok in,
   $1.10 / Mtok out. The aggressive open-weight pricing
   is the headline; the architecture (sparse MoE with
   expert-routing on long-context) is the real signal.
